Use of Health Services after a Myocardial Infarction

Short-term and long-term use of physician consultations and rehospitalizations were studied in 383 myocardial infarction (MI) patients in relation to demographic, medical, and psychological factors. Short-term (i.e. within 6 months post-MI) utilization of physicians was only related to patients' health locus of control. In comparison, a higher number of physician consultations 3-5 years after the MI was independently related to female sex, more non-cardiac limitations before the MI, more complications during hospitalization, less cardiac lifestyle knowledge, and higher levels of anxiety and depression short time after the MI. Every second patient was readmitted to the hospital before the 3-5 years follow-up but only 14% suffered a non-fatal reinfarction. More rehospitalizations were independently related to a higer number of previous hospitalizations for heart disease, more pre-MI cardiac limitations, less cardiac lifestyle knowledge, and higer initial level of emotional distress. Discriminant analysis identified female sex and patients' initial expectations of reduced emotional control as the best predictor variables for a rehospitalization caused by chest pain without a new infarction, whereas a reinfarction was best discriminated by the number of previous hospitalizations for heart disease. We conclude that psychological factors influence health services utilization to a comparable extent as medical factors. These findings may indicate a greater need for long-term professional support in patients with less initial cognitive and emotional control.
