    ABSTRACT

    Purpose: To analyze the determinants of satisfaction and postoperative visual function

    after cataract surgery in 3 settings in The Netherlands.

    Setting: University Hospital Maastricht (outpatient care), Atrium Medical Center Heerlen(inpatient care), and Medical Center Maastricht Annadal (outpatient care), Maastricht,

    The Netherlands.

    Methods:This cross-sectional study consisted of 150 patients of 50 years and older who

    had first-eye phacoemulsification with intraocular lens implantation. Data were collected

    by a written questionnaire. The following parameters were measured: medical outcome,

    postoperative function, patient satisfaction with medical outcome and hospital care,

    and overall patient satisfaction.

    Results: In general, patients were very satisfied (mean score 8.43 on a 10-point scale

    ranging from 1 very bad to 10 excellent). The 3 centers did not differ regarding the

    patient satisfaction (P .092). However, postoperative visual function (P .012),

    counseling (P .010), and waiting time (P .001) were different among the settings.

    Patient satisfaction with hospital care had a stronger correlation with overall satisfaction

    than patient satisfaction with the medical outcome (r 0.669 versus r 0.543,

    respectively).

    Conclusions: A causal model of patient satisfaction was tested, indicating that satisfac-

    tion was related to the patients preoperative expectations and the quality of care given

    during the hospital stay and follow-up at the outpatient clinic. This emphasizes the

    relevance of patient education (to set realistic expectations) and counseling (need for

    care) by hospital staff in a cataract surgery setting. J Cataract Refract Surg 2000; 26:

    It is generally agreed that modern cataract surgery iseffective in terms of postoperative increase in visionand safe with respect to the low incidence of surgical

    complications.1 However, the measurement of visual

    function after cataract surgery is a better outcome mea-

    sure than visual acuity alone.2 Therefore, outcome stud-

    ies in cataract surgery should focus on both functional

    status and quality of life after surgery.3

    Although after cataract surgery, most patients ben-

    efit from an increase in visual acuity and visual function

    and an improvement in quality of life, their satisfaction

    may be limited because of a lack of perceived quality of

    care. By combining the evaluation of functional and

    technical quality-of-care aspects, clinician and patient

    evaluations of quality of care can be related.4

    A general problem of satisfaction studies is the

    high number of satisfied patients, which accounts for

    low sensitivity of measurement methods.5 To im-

    prove the sensitivity of the study, problem definitions

    are based on a classification of satisfaction into 3 di-

    mensions: satisfaction with cure (the medical outcome),satisfaction with care given during hospital stay and

    follow-up in the outpatient clinic, and overall satis-

    faction. A research model was formed to map the

    expected relationships between the research variables

    (Figure 1).

    This study analyzed the determinants of satisfaction

    and postoperative function in patients who had cataract

    surgery. Three treatment settings were compared, pro-

    viding data on cataract surgery on an inpatient and out-

    patient basis.

    Patients and Methods

    The study population consisted of 3 subgroups

    based on the institution at which cataract surgery was

    performed. One group of patients was treated at a gen-

    eral hospital (Atrium Medical Center Heerlen

    [AMCH]) on an inpatient basis, 1 group was treated at a

    private daycare center (Medical Center Maastricht An-

    nadal [MCMA]), and 1 group was treated at an aca-

    demic hospital on an outpatient basis (University

    Hospital Maastricht [UHM]). Inclusion criteria were

    first-eye cataract surgery to prevent bias from earlier ex-

    periences and age older than 50 years. The required

    sample size of 150 patients was calculated by power

    analysis.To correct for an anticipated nonresponse, 235 pa-

    tients were asked to participate in the study. The re-

    sponse rate to the questionnaire was 64% (150 of 235

    patients). Mean age was 77.4 years 7.48 (SD) (range

    54 to 90 years), 74.6 9.74 years (range 51 to 94 years),

    and 72.3 9.95 years (range 52 to 89 years) in the

    UHM, MCMA and AMCH groups, respectively (P.022). The male/female ratio among the 3 settings was

    comparable: 21/30, 27/31, and 16/25, respectively (P.731). There were no significant differences in education

    level (P .727) or civil status (P .253) parameters(Table 1).

    Surgical TechniqueCataract surgery was performed from January

    through July 1997 by 1 of 4 surgeons using a standard

    divide and conquer phacoemulsification technique. A

    3.2 mm corneoscleral incision was made and a poly-

    (methyl methacrylate) intraocular lens (IOL) (SN53,

    Allergan) implanted.

    Outcome MeasuresThe determinants of patient satisfaction were eval-

    uated by analyzing objective medical outcome measure-

    ments and subjective patient evaluations. Medical

    outcome parameters for patient satisfaction were post-

    operative logMAR visual acuity and vision improve-

    ment defined as at least2 lines on the Snellen scale.6 In

    addition, the incidence of intraoperative complications,

    vision in the contralateral eye, and ocular co-morbiditywere recorded. Ocular co-morbidity consisted of glau-

    coma, corneal disease, age-related macular degeneration

    (ARMD), diabetic retinopathy, retinal detachment, am-

    blyopia, and uveitis.

    A questionnaire was sent to patients 6 months after

    surgery to measure subjective patient evaluations. To

    evaluate postoperative function, the following variables

    were studied: ability to perform specific vision-depen-

    dent activities (Dutch version of the VF-14), with 1

    question reflecting overall trouble with vision, 5 ques-

    tions related to the patients opinion of quality of life,

    and 3 questions on subjective general health. Patient

    satisfaction was measured by 3 dimensions: satisfaction

    with medical outcome; satisfaction with care; overall

    satisfaction.

    The VF-14, which has been described in detail,2was

    adapted for use in The Netherlands. Considerable atten-

    tion was given to conceptual and cultural equivalence

    and to ensuring the instrument was translated accurately

    (translation-back translation method) (Table 2). Ques-

    tions 7, 9, and 10 were changed because they referred to

    handwork (crocheting), a game (mahjong), and sports

    (golf) less familiar to the Dutch population. Two

    questions relating to cycling (during the day and

    nighttime) and 1 question on the use of public

    transportation, common activities for the older pop-

    ulation in The Netherlands, were added. Otherwise,

    the questions and scoring were performed as described

    by Steinberg et al.2

    The VF-14 scores ranged from 0(worst level of function) to 100 (best level of func-

    tion/no disability).2,7

    Validity and reliability of the Dutch version of

    VF-14 were tested by an expert panel and in a pilot

    study in a fashion similar to that reported by Alonso

    et al.8 Cronbachs alpha was similar to that in the

    original VF-14 ( 0.98), and factor analysis

    supported the Dutch version of VF-14 to be a single

    index of visual function. The criterion validity of the

    VF-14 instrument was assessed by examining the corre-

    lation between VF-14 scores and visual acuity and be-

    tween VF-14 scores and patient satisfaction with their

    vision. The correlation between the VF-14 and visual

    acuity and between the VF-14 and patient satisfaction

    with vision was 0.28 and 0.64, respectively. These values

    are comparable to those in the study by Steinberg et al.2

    In addition, patients were asked to rate their overall

    amount of trouble with vision. Response options were

    4 none; 3 a little; 2 a moderate amount; 1 a

    great deal.7,9

    Patients opinions about their postoperative quality

    of life and subjective general health were measured on a

    3-point scale. They were asked whether their quality of

    life (self-management, feelings of loneliness, life satisfac-

    tion, activity, happiness) or general health (1 got

    worse, 2 stayed the same, 3 got better) had changed

    postoperatively. Face validity was tested by an expert

    panel and a pilot study among patients.

    Response options for satisfaction with medical out-

    come were 1 very dissatisfied; 2 dissatisfied; 3

    neither satisfied nor dissatisfied; 4 satisfied; 5 very

    satisfied. In addition, patients were asked whether theirvision and visual function had changed as expected. Re-

    sponse options were 3 better than expected; 2 as

    expected; 1 less than expected.

    To evaluate patient satisfaction with care, the

    SERVQUAL service quality measurement scale10 was

    used. This questionnaire was designed to be applicable

    across a broad spectrum of services. It was empirically

    evaluated for its potential usefulness in a hospital service

    environment by Babakus and Mangold.11 Minor

    changes were made to tailor the instrument to the spe-

    cific characteristics of the department of ophthalmol-

    ogy. Translation into Dutch was based on translations

    by Kunst and coauthors.12 Content validity was tested

    by an expert panel and a pilot study among patients as

    described by Babakus and Mangold.11 The final scale

    consisted of 13 quality-perception statements measured

    on a 5-point scale, with endpoints labeled very good

    (score 5) and very poor (score 1). Factor analysis revealed

    3 dimensions: education, counseling, and waiting time.

    Reliability analysis of these dimensions resulted in

    Cronbachs alphas of 0.84, 0.88, and 0.59, respectively.Patients were also asked to rate their satisfaction with

    care on a 5-point scale on which 1 very dissatisfied

    and 5 very satisfied.

    Overall satisfaction was scored on a categorical vi-

    sual analog scale ranging from 1 (very bad) to 10 (excel-

    lent). In addition, a have it again score, based on an

    intention-to-return score developed by Babakus and

    Mangold,11was formulated as follows: If I had to un-

    dergo a second eye cataract surgery, I would want to

    receive my treatment there again. This statement was

    measured on a 5-point scale on which 5 strongly agree

    and 1 strongly disagree.

    Statistical AnalysisDescriptive and inferential data analyses were per-

    formed using the SPSS 7.0. In preparation for data re-

    duction, a correlational analysis was performed. A mean

    relative score [sum score/(number of items missing

    values)] was calculated in scale construction to solve the

    problem of missing values. The research model was

    tested by multiple linear regression. The level of signif-

    icance for this study was P .05.Ordinal data based on multi-item factors were in-

    terpreted as interval data in the statistical analysis as

    described by Tabachnick and Fidell13 and Swanborn.14

    Because various items are related to the same conceptand sum scores are calculated, reliability of this proce-

    dure is high. The assumption of an underlying normally

    distributed continuum was checked by item analyses in

    which the following indicators were taken into account:

    internal consistency (Cronbachs alpha), skewness, kur-

    tosis, median and mean values, and distribution.

    Results

    Response Versus NonresponseResponse and nonresponse groups were compared

    with respect to sex, setting, complications, ocular co-

    morbidity, preoperative and postoperative vision, and

    vision improvement. No significant difference was

    found between respondents and nonrespondents (for

    ordinal variables, 1-way analysis of variance; for nominal

    parameters, chi-square test).

    Objective Medical OutcomeVisual acuity improved in 88.8% of cases (Figure 2,

    Figure 2. (Nijkamp) Improvement in visual acuity, logMAR (solid

    bars preoperative; cross-hatched bars postoperative).

    Table 3). Preoperatively, 91.8% of the patients had a

    visual acuity worse than 20/40 on the Snellen scale; post-

    operatively, the median score was 20/25. There was no

    significant difference among the 3 settings in preopera-

    tive and postoperative visual acuities (P .580; P.710) or improvement in visual acuity (P .229). In 2cases, posterior capsule rupture without vitreous loss

    occurred.

    Medical outcome was correlated to pre-existing oc-

    ular pathology (r 0.264) and preoperative visual acu-ity (r 0.282). The incidence of ocular co-morbidity isshown in Table 3. There was no significant difference

    among settings in the incidence of ocular co-morbidity

    (P .517); 27.3% of the study population sufferedfrom pre-existing ocular pathology.

    Subjective Patient EvaluationsPostoperative function. Mean score for postoperative

    visual function on the Dutch version of the VF-14 was

    80.79 25.31, 92.17 14.53, and 86.73 16.94 for

    AMCH, MCMA, and UHM, respectively (P .012,Table 4). The determinants of visual function were post-

    operative visual acuity (r0.283) and general health(r 0.331). Regression analysis showed no significantrelation between logMAR visual acuity in the contralat-

    eral eye (mean 0.36 0.43) and visual function (P.264).

    The median score for overall trouble with vision was

    3.00, 4.00, and 3.00 for AMCH, MCMA, and UHM,

    respectively (P .023, KruskalWallis). Five patientsfrom the 3 settings stated they were bothered very much

    by their postoperative vision in everyday life (score 1 on

    the overall amount of trouble question). Four of these

    patients had pre-existing ocular pathology (glaucoma,

    ARMD, diabetic retinopathy, or retinal detachment). In

    the other patient, the IOL power was incorrect; the

    achieved minus the predicted refraction was 6.79

    diopters.

    Sixty-one percent of the patients stated their general

    health did not change as a result of the cataract surgery.

    However, 31.5% of patients reported that their general

    health had improved after cataract surgery (mean

    3.40 0.87). No significant difference was found

    among the 3 settings (P .881).Mean quality-of-life scores were 2.22 0.45,

    2.31 0.35, and 2.28 0.39 for AMCH, MCMA, and

    UHM, respectively (P .524), with 62.7% of patientsreporting that their quality of life had improved after

    surgery. In patients who stated their quality of life was

    worse postoperatively, visual acuity did not improve af-

    ter surgery.

    Patients opinions about postoperative quality of life

    were related to subjective general health (r 0.563) andvisual function (r 0.303). Civil status (living togetherversus alone) did not affect the predictive value of a

    patients opinion of quality of life.

    Satisfaction with medical outcome. Scores for meansatisfaction with medical outcome were 4.12 1.17,

    4.51 0.79, and 4.16 0.98 for AMCH, MCMA, and

    UHM, respectively (P .089). Eighty percent of re-spondents gave a score of 4 or 5 (satisfied or very satis-

    fied) on the 5-point scale. Nine patients stated they were

    dissatisfied or very dissatisfied (score 1 or 2) with the

    results of surgery. These patients had pre-existing eye

    disease. The determinants of this satisfaction score were

    analyzed by a series of singular linear regression analyses.

    As proposed in the research model (Figure 1), visual

    function and patient reports of change in the quality of

    life were mediators in the relationship between objective

    medical outcome or general health and satisfaction with

    medical outcome, respectively (Figure 3).

    Perceived quality of care. Mean scores for quality ofcare were 4.45 0.51, 4.48 0.56, and 4.34 0.65

    for AMCH, MCMA, and UHM, respectively (P .43);90.0% of patients reported the quality of care was satis-

    factory (score 4 or 5). Patients evaluated the waitingtime for cataract surgery the least positive aspect of care

    (Table 5). Significant differences were found in waiting-

    time scores among the 3 centers: 2.61 0.83, 3.61

    0.77, and 2.62 0.79 for AMCH, MCMA, and UHM,

    respectively (P .001). Waiting time for cataract sur-

    gery did not predict patient satisfaction with care (P.992).

    The mean scores for patient education were 3.54

    1.01, 3.79 0.80, and 3.43 1.02 for AMCH,

    MCMA, and UHM, respectively (P .120); 20.0% ofpatients rated the education they received as poor (score

    1 or 2).

    Mean scores for patient counseling were 4.25

    0.54, 4.50 0.49, and 4.20 0.58 for AMCH,

    MCMA, and UHM, respectively (P .010). Regres-sion analysis indicated that counseling by ophthalmolo-

    Overall satisfaction. Mean overall satisfactionscores were 8.37 1.30, 8.66 1.24, and 8.18

    1.31 for AMCH, MCMA, and UHM, respectively

    (P .146); 91.0% of respondents wanted to betreated in the same center if they had to have second-

    eye surgery. The median have it again scores were

    4.00, 5.00, and 4.00 for AMCH, MCMA, and UHM,

    respectively (P .083).The following parameters were predictors of overall

    satisfaction: whether preoperative expectations of med-

    ical outcome were met (r 0.407), satisfaction withquality of care (r 0.669), and evaluation of patientcounseling (r 0.674). Patient education and counsel-ing were more strongly correlated with overall satisfac-

    tion than medical outcome (r 0.669 versus r 0.543).

    Discussion

    Studies have proved the usefulness of patient ques-

    tionnaires for outcomes evaluation of cataract sur-

    gery.2,1518 Several instruments have been developed to

    assess subjective visual disability and self-rated quality of

    vision in patients with ocular disease.

    We chose the VF-14 questionnaire, developed by

    the Cataract PORT group, because it has proven test

    retest reliability, responsiveness, and international valid-

    ity in cataract patients specifically.8,9,19 We modified

    the VF-14 for the Dutch population and showed valid-

    ity and reliability comparable to the internationally val-

    idated VF-14 instruments by Alonso et al.8

    Our study found that cataract surgery is an effective

    treatment in terms of improvement in visual acuity,

    postoperative visual function, and patient opinion of

    quality of life. This multidimensional influence of cata-

    ract surgery was manifested in a high rate of satisfaction(80.0%) with medical outcome. These findings are

    comparable to those of previous studies.9,20,21

    The high rate of success achieved by modern cata-

    ract surgery1 has created a situation in which patient

    expectations of postoperative visual function are very

    high; in most cases, such expectations are fulfilled.22

    One must be careful in interpreting these positive results

    with regard to response rates, however. A nonresponse of

    36% can compromise generalization of results. There

    were, however, no significant differences among respon-

    dents and nonrespondents on available data (sex, setting,

    complications, co-morbidity, preoperative and postop-

    erative visual acuities, and vision improvement).

    Satisfaction studies of patients, the consumers of

    care, should also focus on the quality of care given dur-

    ing treatment. The Medical Outcomes Study23 advised

    including the following variables in outcome studies:

    clinical endpoints, functional status, general well-being,

    and satisfaction with care. However, few studies have

    focused on all 4 outcomes.21,24

    Our study compared 3 settings regarding compa-

    rable dimensions of outcome: clinical endpoints, vi-

    sual function, patient opinion of postoperative quality

    of life, subjective general health, and patient satisfaction

    with medical outcome and care. Analysis of variance

    showed significant differences among the groups in age,visual function, patient evaluation of counseling, and

    the waiting time. Although the visual function score was

    significantly better in the MCMA group than the

    AMCH group, determinants of visual function, post-

    operative visual acuity, and general health did not

    differ among the settings. Although age differed signifi-

    cantly among the 3 settings, regression analysis revealed

    that the difference in visual function could not be ex-

    plained by the difference in age. Further research is

    needed to explain the difference in visual function

    among settings.

    The differences in evaluation of patient counseling

    at MCMA and UHM can be explained by the difference

    in the physicianpatient relationship at the 2 settings. At

    UHM, an academic hospital, the patient is treated by

    various doctors. At MCMA, patients are seen by only 1

    or 2 ophthalmologists, which likely benefits the doctor

    patient relationship.

    Patient waiting time also varied significantly among

    the 3 centers. Patients at MCMA had to wait 3 months

    to be treated; however, the waiting time at the other 2settings was about 1 year. The patient evaluations reflect

    this difference. However, no direct relationship was

    found between evaluation of the waiting time and pa-

    tient satisfaction with care. This might be explained by

    the supporting role of patient education; when patients

    are adequately informed about waiting time, they are

    often willing to accept a longer time.

    Multiple linear regression analysis showed that pa-

    tient counseling had more predictive value than medical

    outcome with regard to overall patient satisfaction. This

    emphasizes the relevance of patient support and educa-

    tion by hospital staff in a cataract surgery setting.

    In conclusion, to improve overall patient satisfac-

    tion after cataract surgery, more emphasis should be

    placed on meeting patient expectations of postoperative

    vision and visual function. In general, we believe that

    current medical outcomes of routine cataract surgery

    are excellent and, therefore, quality improvement

    should focus more extensively on patient education and

    counseling.
