Spiking rates of heroin and opioid abuse in Pennsylvania are filling up the state's hospitals at an ever-rising rate, producing a snapshot of just who is abusing these potent drugs in the Commonwealth.

According to the Pennsylvania Health Care Cost Containment Council, the face of the state's opioid crisis, based upon hospital data collected statewide, is that of a 33-year-old person when it comes to those hospitalized for heroin.

The analysis of heroin-related hospitalizations from last year showed about 70 percent of Pa. patients were 20 to 39 years old, with an average age of 33.

Still the heroin crisis is reaching down to younger Pennsylvanians as well, with 2 percent of last year's patients between the ages of 15 to 19.

Meanwhile, those Pennsylvanians overdosing on prescription opioids were much older, with an average age of 54, according to the report.

Most concerning of all is the fact that the statistics only track those people admitted to hospitals.

Those Pennsylvanians who overdose on heroin or opioids and are treated in emergency rooms and then released without a hospital admission -- a very large percentage of overall opioid overdose victims -- aren't counted by the Cost Containment Council report.

Use of illegal heroin, as well as abuse of legal opioids like prescription pain killers, contributed about evenly to the Pa. hospital admissions. But the Rx opioids were a slightly larger contributor to hospitalizations, perhaps because these abusers tend to be older.

Over all, admissions to Pennsylvania hospitals for opioid abuse have increased four-fold since 2010 and cost an estimated $27 million last year, with the sharpest increases in admissions coming in the most recent years, the report showed.

"These new findings continue to stress the devastating impact of drugs on Pennsylvania families, communities and taxpayers, regardless of age, race, gender, income level, or where one lives," Joe Martin, executive director of the Pennsylvania Health Care Cost Containment Council, said in a statement.
